Button Group

Installation

Copy editable source into an initialized application:

pnpm dlx @simurgh-ui/cli add button-group

For package consumption, import from the component subpath and load its optional recipe CSS:

React

import {
  ButtonGroup,
  ButtonGroupText,
  ButtonGroupSeparator,
} from '@simurgh-ui/react/button-group';
import '@simurgh-ui/styles/button-group.css';

Vue

import {
  ButtonGroup,
  ButtonGroupText,
  ButtonGroupSeparator,
} from '@simurgh-ui/vue/button-group';
import '@simurgh-ui/styles/button-group.css';

Angular

import {
  ButtonGroupComponent,
  ButtonGroupTextComponent,
  ButtonGroupSeparatorComponent,
} from '@simurgh-ui/angular/button-group';
import '@simurgh-ui/styles/button-group.css';

Omit the component stylesheet for fully headless styling. CLI-copied components use the local path written to simurgh.json and the copied application styles instead of these package imports.

Purpose

Button Group visually joins related actions while exposing a single named group to assistive technology. Use the text and separator parts for compact labels or for dividing distinct action sets.

Default presentation: styled

The optional component stylesheet provides a complete default recipe, including visual hierarchy and interaction states. Consumers can override semantic tokens or omit the recipe.

Basic usage

Live component Button Group ◆

LeftAlignRight

Anatomy

The public component parts are listed in API surface below. Use only the parts needed by the example; compound components depend on their documented parent/child nesting.

State model

This component exposes no public controlled/uncontrolled state pair. Configure it through the props, events, native attributes, or parent-owned state documented in the API tables.

Give every Button Group an accessible name with aria-label or aria-labelledby. Keep keyboard behavior native to the contained controls; use Toggle Group when the buttons represent persistent selected states.

Examples

React

<ButtonGroup aria-label="Text alignment">
  <Button>Left</Button>
  <Button>Center</Button>
  <Button>Right</Button>
</ButtonGroup>

Vue

<ButtonGroup aria-label="Text alignment">
  <Button>Left</Button>
  <Button>Center</Button>
  <Button>Right</Button>
</ButtonGroup>

Angular

<simurgh-button-group aria-label="Text alignment">
  <simurgh-button>Left</simurgh-button>
  <simurgh-button>Center</simurgh-button>
  <simurgh-button>Right</simurgh-button>
</simurgh-button-group>

Accessibility

Preserve the documented composition and accessible names when wrapping or restyling this component. See accessibility and RTL guidance for keyboard, focus, labeling, and directionality requirements.

API surface

• React exports: ButtonGroup, ButtonGroupText, ButtonGroupSeparator
• Vue exports: ButtonGroup, ButtonGroupText, ButtonGroupSeparator
• Angular exports: ButtonGroupComponent, ButtonGroupTextComponent, ButtonGroupSeparatorComponent

Import these public symbols from the component subpath shown in Installation. Framework-specific props, events, slots, directives, methods, defaults, and native-attribute behavior belong in the API tables on this page; use the linked source only to verify the current implementation.

React API reference

React

An inherited-attributes entry means the component accepts the complete named React native interface, including its event handlers and ARIA and data attributes. Remaining attributes are forwarded to the rendered element unless the component behavior described on this page overrides them.

ButtonGroup

Inherited attributes: HTMLAttributes<HTMLDivElement> & RefAttributes<HTMLDivElement>.

Prop	Type	Default / requirement
children	ReactNode	undefined
orientation	Orientation	'horizontal'
ref	Ref<HTMLDivElement> | undefined	undefined

ButtonGroupText

Inherited attributes: HTMLAttributes<HTMLSpanElement> & RefAttributes<HTMLSpanElement>.

Prop	Type	Default / requirement
children	ReactNode	undefined
ref	Ref<HTMLSpanElement> | undefined	undefined

ButtonGroupSeparator

Inherited attributes: HTMLAttributes<HTMLSpanElement> & RefAttributes<HTMLSpanElement>.

Prop	Type	Default / requirement
children	ReactNode	undefined
orientation	Orientation	'vertical'
ref	Ref<HTMLSpanElement> | undefined	undefined

Vue API reference

Vue

Boolean props without explicit defaults use Vue’s false default. Undeclared attributes follow the fallthrough behavior stated for each component.

ButtonGroup

Vue attribute fallthrough is enabled for the rendered root.

Prop	Type	Default / requirement
orientation	Orientation	'horizontal'

No emitted events.

Slots: default.

Exposed methods: none.

ButtonGroupText

Vue attribute fallthrough is enabled for the rendered root.

No declared props.

No emitted events.

Slots: default.

Exposed methods: none.

ButtonGroupSeparator

Vue attribute fallthrough is enabled for the rendered root.

Prop	Type	Default / requirement
orientation	Orientation	'vertical'

No emitted events.

Slots: none.

Exposed methods: none.

Angular API reference

Angular

Inputs and outputs use their public template names. Public methods are callable through a template reference or ViewChild. Native attributes apply to the documented template root or directive host; they are not automatically forwarded through component hosts.

ButtonGroupComponent

Component selector: simurgh-button-group. The template’s first native element is ng-content. Angular host bindings: { role: 'group', '[attr.aria-orientation]': 'orientation', '[attr.data-slot]': "'button-group'", }.

Input	Type	Default / requirement
orientation	Orientation	'horizontal'

No outputs.

Content projection: default.

No public methods.

ButtonGroupTextComponent

Component selector: simurgh-button-group-text. The template’s first native element is ng-content. Angular host bindings: { '[attr.data-slot]': "'button-group-text'" }.

No inputs.

No outputs.

Content projection: default.

No public methods.

ButtonGroupSeparatorComponent

Component selector: simurgh-button-group-separator. The component has no single native template root. Angular host bindings: { role: 'separator', '[attr.aria-orientation]': 'orientation', '[attr.data-slot]': "'button-group-separator'", }.

Input	Type	Default / requirement
orientation	Orientation	'vertical'

No outputs.

Content projection: none.

No public methods.

Composition contract

Follow the framework example as a structural contract. Root components own shared state; parts that consume that state must stay under the root (or be attached to projected descendants in Angular). Parts described as conditional are optional until their corresponding interaction or semantic region is used. Do not render a state-consuming part by itself.

Framework	Required parent/child relationship	Conditional parts	Supporting types
React	Render ButtonGroup as the ancestor. Nest the listed parts inside that root so they can read its shared state/context.	ButtonGroupText, ButtonGroupSeparator are conditional parts: include only those needed by the documented anatomy. A trigger/control and its matching content/item are required when that interaction is used.	None.
Vue	Render ButtonGroup as the ancestor. Nest the listed parts inside that root so they can read its shared state/context.	ButtonGroupText, ButtonGroupSeparator are conditional parts: include only those needed by the documented anatomy. A trigger/control and its matching content/item are required when that interaction is used.	None.
Angular	Create ButtonGroupComponent first. Attach listed directives to elements inside its projected content; nested component parts must remain inside it.	ButtonGroupTextComponent, ButtonGroupSeparatorComponent are conditional parts: include only those needed by the documented anatomy. A trigger/control and its matching content/item are required when that interaction is used.	None.

Accessible names, descriptions, and form labels remain required whenever the component’s purpose cannot otherwise be determined, even when the corresponding visual part is optional.

Framework parity and differences

The adapters target the same user-visible behavior and accessibility contract. Their public shapes follow each framework’s conventions and are not expected to be symbol-for-symbol identical.

Concern	Contract
Public composition	All adapters export 3 public symbols, with framework-idiomatic names.
State and change events	No controlled state contract; use native attributes, inputs, or events documented above.
Children and content	React uses children; Vue uses the slots listed above; Angular uses the documented content projection selectors.
Native attributes	React forwards the named native interface; Vue follows the stated fallthrough rule; Angular attributes apply to the component host unless an input, directive, or documented native root consumes them.
Imperative access	React forwards native refs; Vue exposes no methods; Angular exposes no public methods.

These differences are intentional adapter design. Behavioral or accessibility differences not stated on this page are parity defects rather than supported variations.

Form integration

This component is not a form control and does not contribute a named value to FormData. Use it to structure or describe a form only when its purpose and accessibility guidance apply.

Supported states

The table distinguishes component behavior from application-owned presentation. “Not supported” means there is no public state contract for that adapter; do not invent one with an undocumented attribute. Keep status and error messages accessible when they are rendered outside the component.

State	React	Vue	Angular
Loading	Not supported by this component API; handle this state in surrounding application UI.	Not supported by this component API; handle this state in surrounding application UI.	Not supported by this component API; handle this state in surrounding application UI.
Empty	Not supported by this component API; handle this state in surrounding application UI.	Not supported by this component API; handle this state in surrounding application UI.	Not supported by this component API; handle this state in surrounding application UI.

Error	Not supported by this component API; handle this state in surrounding application UI.	Not supported by this component API; handle this state in surrounding application UI.	Not supported by this component API; handle this state in surrounding application UI.

Styling contract

Styling contract

The selectors below are used by the published component recipe or emitted consistently by an adapter. Treat these as the supported styling surface. Element order, anonymous wrappers, and undocumented descendants are implementation details and should not be targeted.

Surface	Stable hooks
Recipe classes	No component-specific recipe class; this stylesheet currently imports shared tokens only.
Stable DOM parts	[data-slot="button-group"]
Stable data attributes	[data-slot]
ARIA/state selectors used by the recipe	[aria-orientation]
CSS custom properties consumed	--simurgh-radius

Prefer a semantic token override for theme-wide changes. Use the listed class or part selectors for a component-scoped override. When omitting recipe CSS, preserve state attributes and ARIA semantics even if your replacement styles use different selectors.

Customization

Load the optional component stylesheet for the default recipe, override semantic tokens for broad theme changes, or omit the recipe CSS for headless styling. See theming and styling hooks for import order, selectors, dark mode, RTL, and reduced-motion guidance.
